After upgrading to Window 10, when I start TCMD 17.00.77 x64, pressing F1, or entering the command HELP (with or without arguments), brings up the help application, but with error Code: Unable to download. Unable to open this internet site. The requested site is either unavailable or cannot be found. Please try again later. TCMD.INI has WebHelp=No The resulting help window has no content.
